This morning one of our favorite billionaire Bros in business, Mark Cuban, rang the bell at the New York Stock Exchange to help kick-off Global Entrepreneurship Week. Afterward, the Dallas Mavericks owner headed over to the Squawk on the Street set to discuss his business and economic outlook, along with a whole myriad of subjects ranging from investing in start-ups to buying the Dodgers to just what percentage of his net-worth is cash. The one subject not broached? The NBA lockout. But, hey, can't really blame him for not going there considering the news of the day. If you're remotely curious about how Cuban's business brain ticks, the eight-minute interview is a must-watch. Check it out after the jump.
